Yeah the juvenile payara pictured had black spots on its head. If you guys think its armatus then sounds good to me. Makes sense too since armatus are popping up a lot.

Keep an eye on that Endli. It may eat your payara. Don't underestimate an EndliThe jaw looks a lot like mine, but I can't really tell cuz the pic is kinda blurry. Here's what mine look like and they're armatus.
